Tenchusatsu, I'm sure the 64 GB limit will be breached eventually, but then we're talking beyond K9. 64 GB (36 bit virtual addressing) is what Xeon (P6 core based) supports. Athlon has a similar virtual addressing scheme with different number of bits (I can't recall the number). Looking at slide 6 of the Hammer presentation, Hammer supports full 64 bit address space internally, and the external interface supports 40bit physical address space and 48 bit virtual address space, so the physical address space limit is 1 TB, not 64GB. As far as OS support, I think realistically, we will have to wait for the next major version of Windows, 6.0. BTW, has the real version of Windows 2000 / 64 been released, or is it still a pilot?
